<P>PROBLEM TO BE SOLVED: To eliminate uneven rotational speed that is caused by unstable contact state between a sliding member formed on the top of the protrusions of vibrators and a moving unit, in an oscillatory wave driving device. <P>SOLUTION: A groove is provided on the sliding surface of the sliding member formed on the top of the protrusion of an elastic body, in the oscillatory wave driving device that consists of the vibrators, to the elastic body of which an electromechanical transducing element is adhered and fixed and the sliding member is provided on the top of the protrusions of the elastic body, and the moving unit which is rotatable freely, and being in press contact with the vibrators by a pressing member. <P>COPYRIGHT: (C)2004,JPO |
